Key Features; Scalability And Performance - Lenovo ThinkSystem SR860 Product Manual

Key features

The flexible ThinkSystem SR860 server can scale from two to four Intel Xeon Gold or Platinum processors,
delivering significantly faster performance than the previous generation. Built for standard workloads like
general business applications and server consolidation, it can also accommodate high-growth areas such
as databases and virtualization. The ThinkSystem SR860's agile design permits rapid upgrades for
processors and memory, and its large, flexible storage capacity helps to keep pace with data growth.
With the capability to support up to 48 DIMMs, four sockets, mix-and-match internal storage with up to 16
drives, support for two high-performance GPUs, and a dedicated slot for Gigabit or 10 GbE networking,
the SR860 provides unmatched features and capabilities in a 4U rack-mount design.

Scalability and performance

The SR860 offers numerous features to boost performance, improve scalability and reduce costs:
Supports Gold and Platinum level processors in the Intel Xeon Processor Scalable Family.
Processors supported have up to 28 cores, core speeds of up to 3.6GHz, L3 cache sizes up to 38.5
MB, and TDP ratings of up to 165W.
The SR860's processor mezzanine tray design enables you to start with two processors and 24
DIMM sockets and upgrade to four processors and 48 DIMM sockets when you need it, helping
lower initial costs and manage growth.
Up to four processors, 48 cores, and 96 threads maximize the concurrent execution of
multithreaded applications.
Intelligent and adaptive system performance with Intel Turbo Boost Technology 2.0 allows
processor cores to run at maximum speeds during peak workloads by temporarily going beyond
processor TDP.
Intel Hyper-Threading Technology boosts performance for multithreaded applications by enabling
simultaneous multithreading within each processor core, up to two threads per core.
Intel Virtualization Technology integrates hardware-level virtualization hooks that allow operating
system vendors to better use the hardware for virtualization workloads.
Support for up to 48 TruDDR4 memory DIMMs operating at 2666 MHz means you have the fastest
available memory subsystem and memory capacity of up to 3.0 TB using 48x 64 GB LRDIMMs.
Future processor options are planned to support 128 GB 3DS RDIMMs which will enable the SR860
to support 6.0 TB of high-speed TruDDR4 memory (M-suffix processor support and 3DS RDIMM
support is planned for a future date)
The use of solid-state drives (SSDs) instead of, or along with, traditional spinning drives (HDDs), can
improve I/O performance. An SSD can support up to 100 times more I/O operations per second
(IOPS) than a typical HDD.
Up to 16x 2.5-inch drives -- SAS or SATA HDDs, SAS or SATA SSDs and the new NVMe PCIe SSDs
-- provide a flexible and scalable all-in-one platform to meet your increasing demands.
Support for up to 8 NVMe PCIe SSDs in a 2.5-inch form factor maximizes drive I/O performance, in
terms of throughput, bandwidth, and latency.
New high-speed RAID controllers from Broadcom provide 12 Gb SAS connectivity to the drive
backplanes. A variety of RAID adapters are available, with cache up to 4 GB and support for 16
drives on a single controller.
Support for two high-performance GPUs up to 300W each. GPUs adds additional processing power
to the server.
Supports a new Lenovo patented-design M.2 adapter for convenient operating system boot
functions. Available M.2 adapters support either one M.2 drive or two M.2 drives in a RAID 1
configuration for boot drive performance and reliability.
